(Cl. 234-10) This invention relates to a device for subsequent improvement of the justiiiability of a line already punched, such apparatus being disposed on perforators for :producing punched tapes for controlling matrix setting and line casting machines.

On setting machines having a manually operated keyboard, it is possible subsequently to insert 1A, 1/2 or 1 em quads in a line already composed if it is found at the end of the line that the space quoins are not suicient to justify the line. This occurs particularly when narrow formats lare being set. In such a case the necessary em quad matrices are inserted after the space quoins.

Hitherto it has been difficult, particularly inthe case of narrow formats, to punch tapes to control modern matrix setting and line casting machines. Known perforators for making such punched tapes are admittedly provided with an indicator system which yadds up the numerical values according to the width of the inserted matrices and the minimum and maximum width of the space quoins and indicates the length of the part of the line that has been set, the remainder of the line still unused, and the justiiability of the space quoins inserted in the line (see U.S. patent specications 2,059,250, 2,069,- 240, 2,080,424 and 2,083,570). However, if the indicated justiability of the space quoins introduced was not suiient to justify the completely punched line, the justifiability of the line could hitherto be improved only to a limited extent, a 1A: em quad perforation being punched over the space quoin perforation, and a space quoin and a 1A em quad matrix being released by the resultant new combination f perforations in the automatic setting machine. Frequently, however, the additional 1A em quad matrices are not suiiicient, so that the incorrectly punched line has to be cancelled.

The cancelling operation is time-consuming. The line has to be punched a `second time; the matrix setting and line casting machine controlled by the punched tape is stationary for the period during which the cancelled part of the punched tape passes through it.

Particularly in the composing of narrow formats, an attempt has hitherto been made to obviate this by operating the spacer key after each operation of the space quoin key in the perforator. The spacer key initiates transport of the punched tape by one step and the punching of a transport perforation. If the perforator operator discovered at Ithe end of a punched line that the space quoins and additional 1A em quad matrices were not sufficient to justify the line, he could manually turn the punched tape back and punch in a 1/2 -or 1 em quad perforation as necessary over the space provisionally provided after any space quoin perforations and thus improve the line justiability.

The additional spaces on the punched tape do not interrupt operation of the controlled setting machine since the tape readers of the setting machine are so designed that they do not initiate any function during the reading of such a space.

Although, in many cases, the above-described method avoids cancellation of -a full line, this method of correction is also liable to trouble. It requires a great degree of concentration on the part of the operator in re- States Patent() 3,197,132 Patented July 27, 1965 ice spect of the spacer key, so that his attention is diverted from reading the manuscript. Capacity and setting speed 'are reduced.

To obviate these disadvantages, the object of the invention is to provide an apparatus in perforators for producing punched tapes for controlling matrix ysetting and line casting machines, whereby the justitiability of a line already punched can be subsequently improved in similar manner.

To this end, according to the invention, there are provided between the space quoin key and the device normally operated by a separate tape transport key for punching a transport perforation and providing a space on the punched tape, a switch and mechanical and/or electrical transmission Yelements which, when the switch is closed, result in the punching of an additional transport perforation with a space on the punched tape in addition to the punching of a space quoin perforation on each operation of .the space quoin key.

The Aadvantage of this arrangement is, in particular, that the perforator operator with the device according to the invention can introduce a space on the punched tape only for the setting of narrow formats and without any diversion fromlthe manuscript after each punching of a space quoin.

The introduction Vof the addition-'al transport perforation in the punched tape can be effected simultaneously with the punching yof the space quoin perforation if the perforator punching device is appropriately designed, but preferably follows the punching of the space quoin perforation.

To enable additional em quad perforations to be subsequently made, thepunched tape must be moved backwards. According to the invention it is particularly .advantageous to provide the punched tape drive with a device for the stepwise return transport of the punched tape and to dispose the operating key for the key-operated return transport device contacter in the standard perfor-:ttor keyboard.

With the new apparatus the perforator operator can initiate the punched tape return transport from the perforator keyboard without turning the punched tape back manually.

This apparatus can be complemented by providing an additional repetition key for operating the punched tape return transport device, such repetition key initiating a continuous return of the punched tape for the period of operation of :such key. Y

Although this system gives an appreciable improvement to the stepwise return transport such as to render it automatic, the operation of the perforator can be rendered still more automatic by additionally providing a punched tape reader in the perforator, such reader being so adjusted that it stops the punched tape returntransport device .if a spaceY quoin perforation combination occurs.

In fact, automatic operation is rendered possible if the punched tape return transport stop device is connected to a switching device which on each return transport stop automatically punches a pre-selected justification matrix over the space step and feeds its numerical value to the perforator indicator system adding device.

To enable the required em quad matrices to be selected more rapidly or to facilitate the decision as to whether 1A, 1/2 or l-em quads have to be inserted as justification matrices, an additional counter may be provided which on each operation of the .space quoin key lis advanced by one unit and is cleared to zero when the justification symbol is punched.

Further (full) automatic operation can be obtained if a known electronic computer computes the width of any additional matrices required from the remainder of the line determined by the perforator indicator and not justi- 3- iiable without extra matrices and from the number of introduced space quoins determined by the aforesaid counter and initiates the tape transport and the subsequent punching for the extra matrices.l j

With the apparatus according to the invention the preparation of punched tapes for controlling matrix setting and line casting machines, particularly for the setting of narrow formats, can be greatly simplified. Time-consuming cancellation or correction are thus avoided and the same applies to any diversion of the operators attention from the manuscript. i

Further features, advantages and possible applications of the invention will be apparent from the following description of embodiments given by way of example with reference to the accompanying drawings, in which: Y

FIGURE 1 shows a first exemplilied embodiment of the invention, Y

FIGURE 2, consisting of FIGURES 2a and 2b, shows a modied exemplified embodiment of the invention, andl FIGURE 3, consisting of FIGURES 3a and 3b, shows a further modified exemplified embodiment of the invention for fully automatic operation.

In the illustrations of all the exemplified embodiments like elements have been given like references. All the keys in the three exemplified embodiments are preferably situated in the standard perforator keyboard.

Inthe exemplified embodiment shown in FIGURE 1, an electric or electromagnetic connection constructed according to the invention is shown between a space quoin key 1 and a tape transport key 2 of the perforator. The space quoin key 1 normally initiates the punching of a space quoin combination on the punched tape with appropriate tape transport and the indication of the numerical values corresponding to the minimum and maxi-V mum-width of the space quoin -on a known perforator indicator. The tape transport key 2 normally initiates the punching of a transport perforation with corresponding tape transport. For the sake of clarity, these known normal functions of the keys have not beenpshown.

In order that each operation of the space quoin key may initiate not only the punching of a` space quoin perforation -combination on the punched tape and the delivery'of space quoin numerical values t-o the indicator, but also, after the closure of a switch 3, a following punching of a transport perforation combined with a space on the punched tape for possible subsequent over-punching, aswitch 1a is connected to the space quoin key 1 and is closed on each operation of the space quoin key. The movable contact of the switch 1a is connected to ground. From the switch 1a a lead 1b leads to the switch 3 and to an electromagnetic counter 8. The counter is also connected by'a lead 8b anda common line 90'to the negative pole of a voltage source 91, whose positive pole is at ground potential.

The switch'3, which is operable in anyV desired manner, preferably by means of a key3a on the standard pertorator keyboard, connects a circuit comprising elements 4, 5, 6 and 7 to the line 1b when the switch 3 is closed. The circuit consists essentially of a crystal diode 6 connected in parallel with the relay winding, a condenser connected in series withy relay 4 and diode 6, and a resistor 7 connected in parallel with the series circuit comprising the relay winding'4, diode 6 and the condenser 5. The circuit is connected by its free end to the 1 negative pole of the voltage source 91. Y Y According to the invention, the tape transportkey 2 is combined with an operating magnet 2b which operates the tape transport key when energised. One input 2c of the operating magnet 2b is connected by a working contact 4a of the relay 4to ground, While the other magnet input is connected to the line 9i).

' A return magnet 8a is provided to return the counter 8 to the zero position and one of its inputs is Vconnected to the line 90 while its other input is connected by a line Y 8c Vand a switch 9a operated by a` key 9 'to ground. The

key 9 is advantageously the perforator key normally used for punching the justification symbol. When it is operated, the switch 9a is closed so that voltage is applied to the return magnet 3a.

The circuit arrangement shown in FIGURE 1 operates as follows:

When the switch 3 is closed, the circuit arrangement 4, 5, 6 and 7 is connected to the line 1b. The switch 1a is closed on operation of the space quoin key 1. The counter S is thus advanced'one step and ground potential is applied to the circuit 4, 5, 6 and 7. The condenser 5 is charged since acircuit is closed from ground, the contact 1a of the space quoin key, the switch 3, the condenser 5, the crystal diode 6 to the negative pole of the voltage source 91. The relay 4 is short-circuited by the crystal diode 6 and is therefore not actuated.

If the space quoin key 1 is released so that the switch 1a opens, the condenser 5 discharges through resistor 7 and the winding relay 4, the crystal diode 6 being nonconductive in this direction. The discharge current of the condenser 5 energizes relay 4. The working contact 4a of the relay 4 is closed so that the magnet 2b is energised and in turn actuates the tape transport key 2. The relay remains energised until the condenser 5 is discharged. That is sufficient to initiate the punching of a transport perforation on the punched tape with associated tape transport by means of the tape transport key. Since this operation takes place immediately after operation of the space quoin key 1, the space on the punched tape is situated immediately after the space quoin perforation.

At the end of the line punching operation the counter S shows the number of spaces on the tape provided aS a precautionsuch a number corresponding to the number of space quoins introduced. From this, and from determination of the remainder still to be filled from the perforator indicator, it is possible to estimate or calculate what size of fixed spaces in the form of 1A, 1/z or l-em quads must be introduced for the remainder of the line to be distributed uniformly over the spaces between the words. Y

FIGURE 2 diagrammatically illustrates the circuit arrangement for another embodiment of the invention. The keys 1, 2 and 9 correspond in function to the keys bearing the same references in FIGURE 1, except that the key 2 co-operates with a switch 2a.

In addition, a repetition key 3) is provided with a switch 30aa tape return key 28 with a switch 28a and a justification matrix key for each type of introducible fixed justification matrix, for example a key for each of the 1A, 1/2 and l-em quad matrices. Only one key 42 is shown of the justification matrix keys. The key 42 co-operates with Va switch 42a. The circuit arrangement Y and operation of the other justification matrix keys correspond to the key 42. The movable contacts of switches la, 2a, 9a 28a and 42a are connected to ground.

The punched tape is perforated in known manner by Y punches (not shown) pre-selected or operated directly by code punching magnets.

Three recording means in the form of code punching magnets-magnets 20, 35 and 38are shown in FIGURE 2. The magnet 38 symbolically represents the other code punching magnets, thetotal number of which corresponds to the number of code punching lines used, for example six lines to a six-digit code. For the sake of simplicity it will be assumed that the perforation punched in the punched tape on operation of the magnet 20 corresponds to the combination of perforations for one space quoin, and the perforation punched on operation of the magnet 35 corresponds to the combination of perforations for a given justification matrix, for example a 1A em quad justification matrix. For punching the perforation combinations of other justification matrices, for example 1/2 and 1-em quad matrices, and for punching the letters, other combinations of code punching magnets are operated, if desired with the interposition of a known coding matrix. A magnet 23 is provided for initiating the transport perforation. Any amplifiers required before the magnets have been omitted for the sake of simplicity.

The tape transport by means of the perforator is effected by a drive motor 25, for example a stepping motor, the direction of rotation of which can be reversed by Change-over switches 29a and 2% by reversing the polarity of the field winding 26a.V Instead of a reversible field windinf7 other means may be used to reverse the direction of transport of the punched tape, for example a reversing gear. The change-over switches 29a and 2911 are relay contacts of a relay 29, whose Winding is connected to the switch 23a of the tape return key 28 and the common line 90 leading to the negative pole of the battery 91.

As in the arrangement shown in FIGURE 1, the switch 1a of the space quoin key 1 is connected to the counter 8, and the switch 9a of the justiiication symbol key 9 is connected to the counter return magnet 8a. Counter 8 and return magnet 3a are also connected to the common line 90. By way of line 1b the space quoin key 1 can also act on a bi-stable switching element 18, the resetting input of which is connected by a line 18a to a complementary output of a mono-stable switching element 25. The output of the bi-stable switching element 18 is taken via line 1S!) to an input of the numerical value adding mechanism of the perforator indicator system, an OR-circuit 21 and one input of an AND-circuit 19. The Complementary output of the bi-stable switching element 18 is connected via the switch 3 to a second input of the OR-circuit 21, which input is connected to the switch 2a of the tape transport key 2. A third input of the OR-circuit 21 is connected to the switch 42a of the justification matrix key 42. The output of the OR-circuit 21 is connected to the input of another mono-stable switching element 22. The output of the element 22 is taken via a normally closed contact 29C of the relay 29 and a line 22a to one input of each of the AND-circuits 19 and 34 and the transport perforation magnet 23. A second input of the AND-circuit 34 is connected to the switch 42a of the justification matrix key 42 and is connected via the line 33a to the adding mechanism 1S.

A complementary output of the mono-stable switching element 22 is connected to one normally open contact 23d of the relay 29 in series with the switch 36a of the repetition vkey 39 and by a delay network 24 to the input of the mono-stable switching element 25. The output of the element 25 leads to the changeover switches 29a and 2911 of the field winding 25a of the transport motor 26,

l The outputs of the AND-circuits 19 and 34 are connected to one side of the magnet windings 26 and 35, whose other sides like those of the magnet 23 are connected to the common line 9i?. Thus switch 30a is connected to the ite-setting input of the bi-stable switching element 13.

By means of a changeover Contact 29e of the relay 29 the yadding mechanism 15 of the perforator indicator system is `set to forward or reverse counting. An example of a reversible adding mechanism of this kind is disclosed in U.S. Patent No. 3,083,897. A re-setting input of the adding mechanism 1S is connected to the switch `9a of the key 9.

Tlhe arrangement operates as follows:

On operation .of the space quoin key 1 the switch la is closed, and advances the space quoin counter 8 by one step to indicate the total number `of space quoins introduced into a line, and sets the bi-stable element 1S. By way of the element 13, counting information corresponding to the space quoin width is fed to the adding mechanism 1S ,and a pulse passes to the AND-gate 19. Ihe mono-stable element 212 is also switched over by way of the OR-gate `211 and thus in turn passes information by the closed contact 29C to the other input of the AND- gate 19 so that the AND-gate is opened and the punching magnet is released to punch the space quoin combination. At the same time the magnet 2-3 for punching the transport perforation is also released.

After -a certain time determined by the circuit elements of the mono-stable switching element 22, the element 22 swings back to its initial state so that no current is applied to the magnets and 23. The complementary output of the mono-stable switching element 22 passes a pulse through the delay network 24 to the monostable element which in turn applies current to the transport -m-otor 26 for one tnansport step. During the delay period produced by the delay network 24, the punches can be withdrawn from .the punched tape, for example by return springs.

On the switching back of the mono-stable element 25, its Icomplementary output feeds a pulse to the re-setting input of the bi-stable element 18, so that this element returns to its position of rest.

If the switch -3 is closeds-o that the circuit is prepared for operation of the space quoin key followed lby automatic tape transport, the complementary .output of the Ibi-stable element 18 feeds another pulse via the OR-gate :21 yto the m-ono-stable element 22, whereupon the transport perforation punching magnet 23 is operated a second time by an impulse transmitted by the closed contact 29e. In these conditions the magnet 20 does not produce ,a space quoin perforation, however, since the associated AND-gate 19 remains closed owing to the absence of information from the element 18. The rest of the program is 'as described above.

The .adding mechanism 15 not only adds in known manner the values for the space quoins, but lalso the values of all the introduced*matricesk If the perforator openator then iinds at the end of a yline that too many letters have been introduced, the punched tape transport mech-anism can .be returned by the corresponding number of steps and the value `of the associated matrices can be subtracted in the Iadding mechanism 15, the tape lreturn key `28 and the letter keys corresponding to the excessive number of matrices being operated-simultaneously. This takes pl-ace as follows:

The tape transport key 2 or the `letter keys (not shown) connected in the same way as :the tape transport key, lfeed-1a pulse, via the switch '2a and the OR-gate 21, on each transport step At-o the mono-Stable element 22, which when it returns to its inoperative state passes the pulse on, as described Iabove, to the mono-stable element `25. The relay Z9 is energised via the contact 28a of the tape return key 28 and reverses the transport motor 26 via the vrelay contacts 29a and29b .by reversing the polarity of the `tie-ld Winging 26a, and the motor runs -in the opposite direction, that is, for return transpont. On e-ach swing-over of the mono-stable element 25 a reverse trans- -port step is therefore performed so that on the reverse keying of the last word in the particular line the punched tape -again stops in its position infront of this word. The `changeover contact 29e of the relay.29 switches the adding mechanism 15 to subtraction during the return keying operation so that on actuation of the required letter keys the counted valuesof the reversed matrices ,are deducted. The normally closed contact 29C of the relay 29 opens and prevents the code punching magnets 20, 35, 38 and the transport punching magnet 23 from being operated during .the reverse keying operation.

After the reverse keying operation the excessive Word is cancelled by over-punching in the perforation station. 'If Iaft-er completion of thisloperation it is found by reference to the indicator comprising the adding mechanism 15 .that the justification lrange of the space quoins is not suiiicient to fill Ithe line in this form, 1/4, 1/2 or 1- em quad matrices must be subsequently introduced in addition to the space quoin perforations. -It is easy to determine which of these iixedjustitication matrices is iadapted to` dividing the remainder of the line over the spaces between the words, bydividing the line remainder tion matrix, for example 1A; `1/2 or 1-em quads.

'On the' swinging back of the mono-stable elementZS, its complementary output passes a pulse through `the closed switch 36a of'the key 3f), the closed'contact 29d of the relay k2.9 and the delay network 24to its own input, whereupon the element 2'5 lagain swings over and produces la further .return step of the punched tape trans.- port motor 26.

The key .is advantageously released when the tape transport perforatlicinrafter :the space quoin perforation is situ-ated above therpunches. 'The keys.2 and 2S are also released, 'the relay 29 drops.-

By operation of the Vappropriate justification matrix key the perforation combination for the required justification matrix can now be introduced into the punched tape instead ,of the space after the space quoin perforation combination. If, for example, the `key 42 is operated -for this purpose, a pulse passes the OR-gate 21, .the monostable element 22 and the closed contact 29c"to one in- ,put of the -AND-gate 34 .while the other input of the AND-gateis controlled directly bythe switch 42a. The AND-gate 34 thus conducts and passes current to the magnet 35 of the appropriate justification matrix perforation combination. The counted value of theV subsequently introduced justification matrix is simultaneously determined Vin the adding mechanism of the perforator indicatorVv system so that Vafter completion of the subsequent insertion the justifiability of the line can be checked. Repeated forwardtransport of the punched tape can Ybe produced inA accordance with the above by operation of the keys 2 and 30, the other justification matrix perforations being made in the same way as described above. At the end of the line the key 9 is depressed `to punch the .justification symbol and at the same time the counter 8 and the adding mechanism 15 Yare re-set by means of the magnet 8a.

The arrangement shown in -FIGURE 3 corresponds extensively to that shown in FIGURE 2 in respectof its construction but has been extendedl in'comparison there- Withso that improvement ofthe justifiability of the line can be performed fully automatically.

A computer 37 is provided to evaluate the values at the `end of punching a line for the nonjustifiable remainder of the line (adding mechanism 15.) and for'the total number of introduced spaceV quoins (indicated at `the counter 8). Y

`23 and 30. IBy means of its contact 2a the vkey 2 passes Y A sensing system 31 is provided in front of the perforator punching station (not shown) and senses the perforation of the punched tape 5d and its identification elements are preferably situated one transport step in front of the punches. Reference 17 on the punched tape denotes a transport` perforation and reference 16 denotes, for example, a combination of space quoin perforations.

The sensing mechanism 31 has three outputs a, b, c. At the output a asignal occurs if there is a combination of space quoin perforations, and at the output b a signal occurs if there are line end symbols present, while at the output c there are signals as long as the identification elements encounter any combinations of perforations in punched tape 40. Between the output a of the sensing device 31 and the common line 90 there are connected in series the relay 32 and the normally open contacts 36a and 40d of the relays 36 and 46 respectively. The relayv40 is connected to the output b of the sensing system 31 and the common line 90. The output c ofthe sensing system 31 is connected by a normally open contact 4Gb of the relay 4) tothe output b.

The relay 36 is constructed as a delay relay and is disposed between the common line 90 and the line 22a. In parallel with the normally closed contact 29e of the relay 29 is a normally open contact 32d of the relay 32. By way of a normally open contact 41C of the relay 41,

Y the relay 29 can be connected to earth independently of the tape return key. The relay 41 is connected to the common line 9) and by a key switch 45 to ground.

VIn yparallel with the switch 45 'there are connected in petition key 30 are other normally open contacts 41aV yand 40a of the relays 41 and 40 respectively. The contact 29d of the relay 29 is constructed as a changeover contact, contrary to FIGURE 2. YA changeover contact 32a of the relay 32 is disposed between the switch 30a and the changeover contact 29d. One input of the OR- gate 21 is connected to the changeover contacts 29d and 32a.

Y The key 42 provided in the system shown in FIGURE gsis eliminated. Its function is performed by the selector Otherwise the circuits according to FIGURES 2 and 3 correspond. i

The operation of the system shown in FIGURE 3 corresponds exactly to that shown in FIGURE 2 in respect of punching of the line, punched tape return transport in the event of an excessive number of letters being introduced, .and over-punching of the excessive word or To the computer there leads a line 9b from the contact 9a of the key 9 for the line end symbol, a line 1b from 'the contactV 1a of the space quoin key 1 and a line 15a from the output-of the adding mechanism 15. The computer 37 is connected to ground by a normallyY open contact 41d of a relay 41.V The output of the computer 37 is connected by-the line 37a to the input'of Va justification Y matrix selector 33for example-an'electrically controllable steppingmechanism, a relay network'or an equivalent electronic arrangement-which is connected to earth 'by-the normallyopen contact 732b of a relay 32. One output of the selector 33 isconnectedto the input of.' the `-AND-'gate 34 in front of the code punching magnet V35.

y Further outputs of the selector are connected (in manner not shown) tothe AND-gates, of other cdepunching magnets or of combinations of such magnets. Each output of the selector is associated Ywith a particular justificapart of aV word, so that it is not necessary to discuss these operations again.

If, after a line has been punched and any excessive letters have been cancelled by over-punching, it-is found Vthat justification matrices must be subsequently introduced to enable the line to be justified, the operator presses the key 45 so that the relay 41 pulls up and holds itselfby its normally open .contact 41b and` normally closed contact 4de. Closure of the contact 41d operates the computer Y tion matrix, for example r-em justification matrices.

The circuit of the relay.29 is closed by the closed con- Vtact 40aby Vthe Contact 41C, and the relay 29 pulls up.

The contacts 29a and 29b Vreverse the polarity of the field winding V26a of the transport motor26 to reverse transport; The changeover Contact 29d, the contact 32a and the closed contact 41a connect the complementary output of the mono-stable element 25 to the input of the delay network 24.

If the tape transport key 2 is then pressed and the switch 2a closed, a pulse passes through the OR-gate 2i to the mono-stable element 22. Undesired punching as a result of the changeover of the element 22 is prevented since the -contact 29C is opened. The complementary output of the element 22 feeds a pulse to the delay network 24 and to the mono-stable element 25 so that from the output of the element 25 the motor 26 receives current for a reverse transport step. On the switch back the element 25 feeds a pulse via the contacts 41a, 32a and 29d and the delay element 24 to its own input so that it swings again and initiates another reverse step of the transport motor 26.

Return transport continues until a combination of space quoin combinations 16 comes beneath the identification elements of the sensing system 31 and consequently there appears at the output a of the sensing system a signal which actuates the relay 32 by means of contacts 36a and 40d. The changeover contact 32a breaks the connection between the complementary output of the mono-stable element 25 and the input of the delay network 24, and the punched tape 50 stops. The pulse occurring at the complementary output of the element 2S when it switches back ris fed by the contacts 41a and 32a to the OR-gate 21 and then to the input of the mono-stable element 22. The element 22 switches over and its output feeds a pulse through the closed contact 32d to the input of the AND- gate 34. The other input of the AND-gate is controlled by the matrix selector 33 by the closure of the contact 32h.

The AND-gate 34 thus conducts and feeds current to the code punching magnet 35. The code perforation combination for the justification matrix determined by the computer 37 and selected at the selector 33 is punched in .the tape O at the blank space after the space quoin combination. The numerical value of the selected subsequently inserted justification matrix is simultaneously detected in the adding mechanism 1.5 so that the justifiability of the line can be checked after the completion of the subsequent insertion process. The pulse delivered by the output of the mono-stable element 22 causes the relay 36 to be energized with a delay so that the contact 36a is opened and the relay 32 drops. The changeover contact 32a makes the connection from the complementa-ry output of the mono-stable element 25 to the input of the delay circuit 24 again and when the mono-stable element 22 swings back the element 25 swings by way of the delay network 24. Contacts 32b and 32d have opened. The punched tape vruns back further, the relay 35 dropping again. As soon `as the sensing system 31 finds another combination of space quoin perforations, the above-described operation is repeated.

This takes place until the sensing system 31 iinds the line end symbol of the preceding line on the punched tape 50 and energises the relay 40 via its output b. The relay 4t? actuates the contact 49e and causes the relay 41 to drop, which in turn does the' same to the relay 29 by the contact 41C. The contacts 29a and 2% change the transport motor 26 over to forward. By means of the contact 46a of the relay it? to complementary output of the mono-stable element 25 is connected by the contacts 32a and 29d and the OR-gate 21 to the input of the monostable element 22 so that the forward transport continues to operate. During forward transport the relay 40 holds itself by its contact 40h for as long as the sensing system 31 finds punch code combinations on the punched tape and by opening of the contact 40d prevents the relay 32 from pulling up aga-in when the space quoin perforation combinations pass the sensing system 3ft. The relay Sti drops as soon as the end of the last line punched is reached, and by the opening of its contact 49a stops the repeated forward transport.

By means of the key 9 it is now possible (in conventional manner not illustrated) to punch the justiiication symbol. mechanism 15 and the -computer 37 are re-set. cuit arrangement is restored to its original state.
